I am not used to the mac system fully yet. I had to scan in some items and email them. well 21 files was over 25 meg so not able to attach. So thought I use the built in compress feature. Found folder with the 21 items in it. right clicked and compress. So it created a 1k zip file and emptied the original folder! I failed to make a back up of the folder so lost it all. What happened?
